Ipwatchd 告诉我发生了冲突,但我不明白。据我所知,没有冲突。我读错消息了吗?
它是一台 Xen 机器,具有以下网络接口:
- 桥接器“eth0”(00:25:90:06:db:1c),包含 peth0(00:25:90:06:db:1c,相同地址):89.188.xy
- eth1(00:25:90:06:db:1d):10.0.0.2
事实上,桥接器eth0
和物理以太网都是peth0
Xen 4.0 的特性。
ipwatchd 消息是:
MAC address 0:25:90:6:db:1c causes IP conflict with address 10.0.0.2 set on interface eth1 - passive mode - reply not sent
提到的 MAC 是 eth0 (peth0) 的 MAC。10.0.0.2 地址是 00:25:90:06:db:1d。00:25:90:06:db:1c 没有 10.0.0.2,并且不冲突。
那么,这条信息意味着什么呢?
